Magnesium Hydroxide Flame Retardants (MDH)

The good news: magnesium hydroxide is able to take over in the higher temperatures where alumina trihydrate (ATH) leaves off. While functioning in the exact same manner as alumina trihydrate, there is one key difference: magnesium hydroxide undergoes endothermic decomposition when water is released at 330°C or 626°F. That means it is thermally stable at temperatures up to 110°C higher than alumina trihydrate.
